I work from home and we have plenty of food and stuff. We were stranded out here for 4 days in mid January.

Luckily we have a gas fireplace so if the power goes out, we can stay warm. However, if it's out for more than 8 hours or so, I will start losing fish...

If you have a large fish tank on a stand, you can place a candle, (or use 2 if larger than 55g), inside the stand and close the doors, (if there are any). Our power was out for quite some time and that helped keep the water warm.

They'll hold temperature for a lot longer than 8 hours, that's not the issue.

With the power off, there's no surface agitation and eventually the fish start to suffocate due to lack of oxygen.

The temp in mine was dropping too rapidly, which is why I suggested the use of candles, (I didn't know if you had ever tried that before).

None of my tanks are heavily planted anymore, (and no CO2). What would be your suggestion regarding surface agitation? I think that our power was out for 6 hours max and I didn't really do anything about that.

The temp shouldn't drop much at all over the first few hours since there's no circulation or surface agitation. My 55G could go without heat for 12-14 hours and only drop a few degrees. That being said, the area of the house where they are isn't gonna drop much below 68 given its proximity to the fireplace.

I've considered getting battery-powered air pumps but they've been out of stock everywhere and I haven't gotten around to ordering them online.

Other than that, I don't really know what else to do.

And if you don't have a lot of plants, temperature would probably be a bigger problem for you anyway.

The temp in my 55g was dropping a few degrees every hour before I added the candle. Of course, it's located against an exterior wall, (sort of, our garage is on the other side of the wall). My other 2 tanks are small and the temps didn't fluctuate too much.

I would probably look into getting battery-powered air pumps, but I plan on selling the tanks soon.

We have a fireplace, but it's electric. A lot of good that does when you lose power, huh?
